Control and Power Supply System for at Least Two Airplane Seats

1. A power supply system for actuators of at least two airplane seats, comprising: first actuators of a first aircraft seat; second actuators of a second aircraft seat; a common control unit; at least two power supply units; and a data link device connecting said first and second actuators to said common control unit and said power supply units such that each of said actuators can be supplied with power from said two power supply units and such that upon failure of said control unit at least one of said actuators takes over functioning of said control unit with the respective actuator being equipped with corresponding software, said data link device forming a ring bus convertible into a structure with two tap lines upon system malfunction.

2. A power supply system according to claim 1 wherein several of said actuators take over functioning of said control unit by distributed intelligence of said actuators.

3. A power supply system according to claim 1 wherein all of said actuators take over functioning of said control unit by distributed intelligence of said actuators.

4. A power supply system according to claim 1 wherein the two aircraft seats are adjacent to one another.

5. A control and power supply system of at least two aircraft seats, comprising: first actuators of a first aircraft seat; second actuators of a second aircraft seat; a common control unit; a data link device connecting said first and second actuators to said common control unit and all of said actuators in series, said data link device forming a ring bus convertible into a structure with two tap lines upon system malfunctioning; and elements in each of said actuators for interrupting incoming and outgoing lines to the respective actuator.

6. A control power supply system according to claim 5 wherein for each of said actuators, two of said elements are provided for data lines and two of said elements are provided for power supply lines.

7. A control power supply system according to claim 5 wherein the two aircraft seats are adjacent to one another.
